System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

At some point in any software project, you will need to share your code with other developers. If you’re using Git for source control, there are three primary options: Github, Bitbucket, or Gitlab. Understanding the differences and tradeoffs between these three repository management platforms is vital to choosing the best option for your team.

Managing branches

Create and push a new branch

• Before creating a new branch, pull the changes from upstream. Your master needs to be up to date.

  $ git pull

• Create the branch on your local machine and switch onto this new branch

#1.Updates all packages the the latest version available.

sudo yum -y update

#2.Package Dependencies before installing RabbitMq

• erlang
• socat
• logrotate

#3.Enable the EPEL repository

Centralised logging for Docker containers running Spring Boot applications

Log flow through the system

About

We have a bunch of Spring Boot apps running in various Docker containers and wanted a centralised place to view the logs

We summarize the performance characteristics of classic algorithms and data structures for sorting, priority queues, symbol tables, and graph processing.

We also summarize some of the mathematics useful in the analysis of algorithms, including commonly encountered functions, useful formulas and appoximations, properties of logarithms, order-of-growth notation, and solutions to divide-and-conquer recurrences.



Sorting. The table below summarizes the number of compares for a variety of sorting algorithms, as implemented in this textbook. It includes leading constants but ignores lower-order terms.
